Walmart offers the 3-Piece Prism Rug Set for $39.47. Opt for free Site-to-Store pickup to avoid the $4.97 shipping charge. That's tied with our March mention and an extremely low price for three such rugs. (Similar rug sets cost $60 or more elsewhere.) They feature rubber backs and are made of stain-resistant nylon. The set includes a 20x32" rug, 20x60" rug, and 59x78" rug.
